Shut Up and Pay !!!

I took out a contract in September, it is R549 for 3 months and then revert to R699, however Webafrica deducted R849 yesterday?

The response I got from Webafrica: Zandile: Unfortunately, they increased the prices and we apologies for any inconvenience. Zandile: At the end of the day you need to pay so use the service.
